Description
Technical Field
The invention relates to the technical field of fixed supports, in particular to a fixed support device capable of lengthening a thermal ablation temperature measuring needle.
Background
Treatment methods that apply chemical or thermal methods directed at the local lesions under imaging techniques to eradicate or destroy the local lesion tissue are known as thermal ablation treatments. As a high and new treatment technique combining modern physics and medicine, in-situ thermal ablation techniques represented by radio frequency ablation and microwave ablation have been widely used in the past 20 years. The advantages of minimally invasive, safe, high operability, good repeatability and the like are achieved, and more attention is paid to the clinical use. At present, the thermal ablation is mainly used for the ablation of solid tumors of organs such as liver, kidney, lung, thyroid and the like.
The radio frequency ablation and the microwave ablation are both to puncture a radio frequency electrode needle or a microwave antenna into target tissues by utilizing image guidance, and generate high temperature in a short time by different principles, so that the tissues are coagulated and necrotized (the protein denaturation temperature is 60 ℃ or more), and the surrounding tissues are little or not damaged, thereby achieving the purpose of treatment. The acquisition of the temperature field distribution in the thermal ablation treatment is of great significance in judging the treatment effect of thermal ablation and subsequent research.
In ex vivo, in vivo and clinical experiments, the insertion of a thermocouple temperature probe into the target tissue of interest to obtain the temperature field distribution is the most accurate and convenient way. In order to capture the complete temperature field distribution, the temperature probe tip and the ablation antenna tip should be placed on the same line. However, in actual operation, the mode of inserting the temperature measuring needle is quite unreasonable, and the temperature measuring needle is mainly judged by naked eyes and is subjectively inserted, and the temperature measuring needle is easy to deviate from the position of a preset target tissue in the ablation process, so that the data of the temperature measuring needle is meaningless. Therefore, the problem that the tip of the temperature measuring needle and the tip of the ablation antenna are positioned in the same straight line is still to be solved in the prior art.
